Question

what is an iso 8? give proper answer. if not i will report

Answer 1

It's a cleanroom classification. The primary authority in the US and Canada is the ISO classification system ISO 14644-1. This standard includes the cleanroom classes ISO 1, ISO 2, ISO 3, ISO 4, ISO 5, ISO 6, ISO 7, ISO 8 and ISO 9, with ISO 1 being the “cleanest” and ISO 9 the “dirtiest” class (but still cleaner than a regular room). sorry if this was not what you were looking for
